And now it only remains for me to say that I think it is a very grave question for the people of this Union to consider, whether, in view of the fact that this slavery question has been the only one that has ever endangered our Republican institutions, the only one that has ever threatened or menaced a dissolution of the Union, that has ever disturbed us in such a way as to make us fear for the perpetuity of our liberty,--in view of these facts, I think it is an exceedingly interesting and important question for this people to consider whether we shall engage in the policy of acquiring additional territory, discarding altogether from our consideration, while obtaining new territory, the question how it may affect us in regard to this, the only endangering element to our liberties and national greatness. The Judge's view has been expressed. I, in my answer to his question, have expressed mine. I think it will become an important and practical question. Our views are before the public. I am willing and anxious that they should consider them fully; that they should turn it about and consider the importance of the question, and arrive at a just conclusion as to whether it is or is not wise in the people of this Union, in the acquisition of new territory, to consider whether it will add to the disturbance that is existing amongst us--whether it will add to the one only danger that has ever threatened the perpetuity of the Union or our own liberties. I think it is extremely important that they shall decide, and rightly decide, that question before entering upon that policy. And now, my friends, having said the little I wish to say upon this head, whether I have occupied the whole of the remnant of my time or not, I believe I could not enter upon any new topic so as to treat it fully, without transcending my time, which I would not for a moment think of doing. I give way to Judge Douglas. SIXTH JOINT DEBATE, AT QUINCY, OCTOBER 13, 1858. LADIES AND GENTLEMEN: I have had no immediate conference with Judge Douglas, but I will venture to say that he and I will perfectly agree that your entire silence, both when I speak and when he speaks, will be most agreeable to us. In the month of May, 1856, the elements in the State of Illinois which have since been consolidated into the Republican party assembled together in a State Convention at Bloomington. They adopted at that time what, in political language, is called a platform. In June of the same year the elements of the Republican party in the nation assembled together in a National Convention at Philadelphia. They adopted what is called the National Platform. In June, 1858,--the present year,--the Republicans of Illinois reassembled at Springfield, in State Convention, and adopted again their platform, as I suppose not differing in any essential particular from either of the former ones, but perhaps adding something in relation to the new developments of political progress in the country.
